90-Second Read: Hantavirus Not New Pandemic Threat But Risks Should Not Be Ignored - Specialist

In the Americas, certain Hantavirus strains can cause Hantavirus Pulmonary Syndrome (HPS), a severe condition involving fluid accumulation in the lungs that may lead to breathing difficulties and respiratory failure. According to Dr Lee, Hantavirus infections are commonly linked to exposure to environments contaminated by infected rodents, like rats and mice and the virus may spread when tiny particles from rodent urine, saliva or droppings become airborne and inhaled. Although Malaysia has not reported any Hantavirus outbreaks, the recent global attention to the virus serves as an important reminder that rodent-borne infections should not be overlooked.

In Europe and Asia, some strains are more commonly associated with kidney-related complications and bleeding disorders. In rare situations, transmission may also occur through rodent bites or scratches. Therefore, Dr Lee advises against dry sweeping rodent-infested areas such as abandoned buildings, dusty warehouses, or long-neglected areas.

Instead, contaminated areas should first be sprayed with disinfectant, left for several minutes before being wiped using a damp cloth, he said. Simple preventive habits and safe cleaning practices can significantly reduce exposure risks. He also encourages simple preventive measures such as wearing gloves and masks during cleaning, disposing of waste properly and maintaining good ventilation.
